- a portable mobile unit according to a first embodiment of the invention will be described below with reference to FIGS. 1 - 9 .
- This portable mobile unit can reproduce a plurality of data (musical data etc.) stored therein. Further, provided with a charge condition detector (hereinafter referred to as “charge detector”) for detecting a condition of a battery being charged, the portable mobile unit can announce, by means of music selected by the user, that charging is being performed by starting reproduction of data when a start of the charging is detected by the charge detector.
- FIG. 2 is a block diagram showing the configuration of the portable mobile unit according to the first embodiment.
- Reference numeral 201 denotes a radio frequency circuit (hereinafter referred to as “RF circuit”) having a transmission/reception function; 202 , an audio circuit; 203 , a controller for controlling the entire portable mobile unit; 204 , an alarm device for alarming the user by sound or vibration; 205 , a memory for storing programs necessary for operation of cellular phone functions, setting data, and data of musical information to be used for reproducing music; 208 , a battery (rechargeable battery); 206 , an external power input terminal to be used for charging the battery 208 ; and 207 , a charging circuit for charging the battery 208 .
- Reference numeral 209 denotes a charge detector for detecting a charging state of the battery 208 .
- Examples of the data (musical data etc.) are sound data, text data, figure data, and video data.
- Examples of sound data are music, natural sound (e.g., sound of a water flow, a song of a bird, chirping of insects and a cry of an animal such as meow, bow-wow, moo, etc.), and artificial sound (e.g., a ring of a bell or a chime and a beep.
- the information of the plurality of data (musical data etc.) are stored in the memory 205 .
- the function of reproducing the plurality of data (musical data etc.) is started by either predetermined manipulations of the user on the input keys 105 and the shift/decision keys 104 or a transition of the portable mobile unit to a predetermined state
- the plurality of data (musical data etc.) stored in the memory 205 are accessed sequentially by the controller 203 and reproduced as sound.
- the route of acquiring information of the above kind data is prepared and stored in the portable mobile unit in advance, downloaded from an external system, or acquired in other ways.
- the controller 203 inquires of the charge detector 209 whether charging has been started and starts reproduction of the data (musical data etc.) by the above method upon detection of a start of charging.
- FIG. 3 is a flowchart showing a process according to this embodiment.
- a battery 208 is mounted in the portable mobile unit capable of reproducing a plurality of data stored therein and an AC adapter is connected to it at step 301 to charge the battery 208 , preliminary charging is performed at step 302 and a red LED is turned on at step 303 .
- the controller 203 inquires of the charge detector 209 whether charging has started. If charging is going on (yes), the process goes to step 305 (start of confirmation of an automatic reproduction mode) and main charging is started at step 312 . A method for setting the automatic reproduction mode will be described later. If charging has not started (no), the process goes to step 310 , where occurrence of an error is announced. At step 311 , the charging operation is stopped.
- step 306 the controller 203 inquires of the memory 205 whether the automatic reproduction mode is set. If the automatic reproduction mode is set (yes), the automatic reproduction mode is started at step 307 , whereby step (A) is established in which musical information stored in the memory 205 is reproduced and output as sound from the receiver 102 and/or the alarm means 204 . If the automatic reproduction mode is not set (no), the start of the automatic reproduction mode is prohibited at step 308 . This is done by refraining from activating a program for the automatic reproduction function.
- the portable mobile unit may be configured in such a manner that the reproduction time of data (musical data) is set at an arbitrary time.
- FIG. 4 is a flowchart showing a process corresponding to this case.
- FIG. 8A shows a display example of alarm notification corresponding to this case.
- step 404 If the reproduction time has reached the arbitrary preset time (no), alarm notification is performed at step 404 by displaying a picture as shown in FIG. 8A on the display 103 and the automatic reproduction is stopped at step 405 . On the other hand, if the reproduction time has not reached the arbitrary preset time yet (yes), the process returns to step 401 , where the automatic reproduction is continued. Since the user can set the reproduction time arbitrarily, selection can be made between an operation that data is reproduced for about one minute at the start of charging for only the notification purpose and an operation that data is reproduced for a desired time to allow the user to enjoy music.
- the device for performing the alarm notification is not limited to the display 103 and may be performed by at least one of the display 103 , the receiver 102 , and the alarm device 204 .
- the alarm notification is performed after the execution of step 403 before the stop of the automatic reproduction.
- the automatic reproduction may be stopped without performing the alarm notification.
- reproduction of data may be stopped when the charge detector 209 detects that charging of the battery has been suspended after the data reproduction has started upon detection of a start of the charging by the charge detector 209 .
- FIG. 5 is a flowchart showing a process corresponding to this case.
- FIGS. 8B and 8C show display examples of alarm notification corresponding to this case.
- step 504 start of a check as to whether the charging has completed. If it is judged at step 503 that the charging is not being performed (no), alarm notification is performed at step 506 by displaying a picture as shown in FIG. 8B on the display 103 and the automatic reproduction is stopped at step 507 .
- step 505 the controller 503 inquires of the charge detector 209 whether the battery 208 has been charged up. If the battery 208 has been charged up (yes), alarm notification is performed at step 506 by displaying a picture as shown in FIG. 8C on the display 103 and the automatic reproduction is stopped at step 507 . At this time, an alarm sound may be generated before stopping the reproduction of data (music). For example, a peep as an alarm sound may be generated several seconds before stopping the reproduction of data (music). This allows the user to know in advance an approaching stop of reproduction of data (music) at the time of a completion or suspension of charging. If it is judged at step 505 that the battery 208 has not been charged up yet (no), the process returns to step 501 , where the automatic reproduction is continued.
- data can be stopped automatically when charging of the battery 208 has been completed or suspended.
- the portable mobile unit may be configured in such a manner that when charging of the battery 208 has been stopped, the charge detector 209 recognizes whether the charging has been stopped due to charging-up of the battery 208 or the user's interruptive manipulation and the notification method is changed depending on the cause. For example, after the judgment at step 505 , a second notification sound may be output from the alarm device 204 as the alarm notification at step 506 . If charging is stopped though it is judged at step 505 that the battery 208 has not been charged up yet, a judgment can be made that the charging has been stopped due to the user's interruptive manipulation.
- notification may be made by the second notification sound, that is, a notification sound that is different from an ordinary notification sound. This enables discrimination from a reproduction sound of data (music) that is generated at the time of completion of charging, that is, discrimination between completion and suspension of charging.
- the device for performing the alarm notification is not limited to the display 103 and may be performed by at least one of the display 103 , the receiver 102 , and the alarm device 204 .
- the alarm notification is performed after the judgment at step 503 or 505 before the stop of the automatic reproduction.
- the automatic reproduction may be stopped without performing the alarm notification.
- step (A) in FIG. 3 may be a combination of the processes of FIGS. 4 and 5.
- the process of FIG. 6 will be described below. Steps (A) to step 505 (inquiry about whether the battery 208 has been charged up) are the same as shown in FIG. 5, steps 402 and 403 are the same as shown in FIG. 4, and the alarm notification step is the same as shown in FIG. 4 and 5 . Therefore, those steps will not be described here again. If it is judged at step 505 that the battery 208 has not been charged up yet (no), the process goes to step 402 (start of a check of reproduction time). If the battery 208 has been charged up (yes), alarm notification is performed at step 601 and the automatic reproduction is stopped at step 602 .
- the portable mobile unit may be configured in such a manner that the data reproduction start function can be set and cancelled selectively by the user so that the user cancel the data reproduction start function at the time of detection of a start of charging of the battery 208 if the user does not want reproduction of data. Setting should be so made as to allow the user to set or cancel the data reproduction start function on a menu picture.
- FIG. 7 shows exemplary display pictures. A method for setting the automatic reproduction mode according to pictures displayed on the display 103 will be described with reference to FIG. 7. In a reception standby state, the picture of part ( a ) of FIG. 7 is displayed.
- Automatic reproduction mode setting is included in the functions of the item “6: Display and function settings.” If the numeral key “6” of the input keys 105 is depressed, the picture of part ( b ) of FIG. 7 appears.

Abstract
Conventional portable mobile units have a problem that the user cannot enjoy a built-in music reproduction function at a start of charging a battery. Further, no consideration is given to the control of the music reproduction function to be performed when the remaining power of the battery is small. According to the invention, a portable mobile unit capable of reproducing data (musical data etc.) stored therein is provided with a charge detector for detecting a charging condition of a battery or a remaining power detector for detecting remaining power of a battery. The start of data reproduction is enabled when a start of battery charging is detected, or it is prohibited when remaining power of the battery is smaller than a preset value. This enables not only notification using music selected by the user at the time of charging but also power saving when the remaining power of the battery is small.
Description
- 1. Field of the Invention
- The present invention relates to a portable mobile unit capable of reproducing a plurality of data stored therein such as musical data. In particular, the invention relates to a portable mobile unit that can improve ease of use during charging and increase the speech time.
- 2. Description of the Related Art
- In an ordinary state, a portable mobile unit operates using a battery as a power source. Therefore, after a portable mobile unit has been used for a certain period, the amount of energy stored in the battery becomes small and charging of the battery becomes necessary. Conventional portable mobile units visually announce ongoing, completion, etc. of charging by means of a message on a display or a light-emitting device (e.g., an LED). Functions that operate with detection of charging of a battery include a function of switching the call arrival announcing method from one using sound to one using vibration and a function of controlling an auto power on/off function capable of turning on or off the power of a portable mobile unit after a lapse of a predetermined time. In this manner, no limitation is imposed on added functions during charging because it is not necessary to take power saving into consideration during charging. Japanese Unexamined Patent Publication No. Hei. 11-68648 relates this conventional technique. In this publication, a charging connection detecting means for detecting a connection state between a power source and a charging circuit for a battery (rechargeable battery). With a detection result used as a parameter, control can be performed so that the call arrival announcing method is switched from one using vibration of a vibrator to one using sound output of a sounder, an auto power on/off function of on/off-controlling the supply of power to individual circuits of a portable mobile unit is switched from on to off, or a phone-answering function is switched.
- Portable mobile units of such types that a memory for reproduction of music is provided and plural pieces of favorite music that are stored in the memory can be reproduced at a desired time for the user's enjoyment or can be reproduced as sound for announcing call arrival are now spreading. That is, attempts are being made to allow the user to enjoy his favorite music.
- On the other hand, there is a technique that, to secure a sufficient speech time, restricts (including stopping) operation of function blocks that are irrelevant to communication when the remaining power of a battery has become small. Examples of the function blocks irrelevant to communication are an illumination device such as a screen illumination, a display, and a musical information storage block for reproduction of music (added function). Among those techniques is a technique of restricting basic functions of a portable mobile unit (Japanese Unexamined Patent Publication No. 2000-253142). In this technique, the power consumption can be controlled on a function block basis. When the remaining power of a battery has become small during a call, the power consumption is reduced by restricting (including stopping) operation of an illumination device such as a screen illumination, a display, and even a transmitting section (during reception).
- Japanese Unexamined Patent Publication No. 2000-308269 discloses a technique of restricting added functions. In this technique, in a portable mobile unit having a musical information storage section for reproduction of music using an external storage medium such as a magnetic disk, operation of the block of the musical information storage section is stopped when the remaining power of a battery has become small and the power consumption is thereby reduced.
- However, the above-described techniques have the following problems.
- First, the conventional notification relating to, for example, a start or completion of charging is performed visually by means of a message on a display, a light-emitting device, or the like. Therefore, the user cannot be notified unless the portable mobile unit is located at such a position as to be seen by the user.
- Second, since the music reproduction function as a built-in function is not activated automatically when charging of a battery is started, the user cannot be notified by means of his favorite music.
- Third, although it has already been done to stop operation of a function when the remaining power of a battery is small, no technique is available that prohibits activation of a function even when the user has made a manipulation for activating the function.
- Fourth, although the music reproduction function using a built-in memory does not exist as a function block, music is output from a speaker or the like and power is consumed if it is activated. No consideration is given to increase of the speech-possible time in the form of restriction to an item that does not exist as a function block.
- An object of the present invention is to provide a portable mobile unit that is easy to use and can increase the speech time.
- A first aspect of the invention provides a portable mobile unit comprising a memory for storing data; a controller for controlling reproduction of the stored data; and a charge detector for detecting a charging state of a battery, wherein the controller starts reproduction of the data when the charge detector detects that charging of the battery has started.
- In a first preferred embodiment, the controller performs control so that the reproduction of the data is stopped after a lapse of an arbitrary preset time from the start of the reproduction of the data.
- In a second preferred embodiment, the controller performs control so that the reproduction of the data is stopped when the charge detector detects suspension of the charging of the battery after the start of the reproduction of the data.
- In a third preferred embodiment, the charge detector is so configured as to recognize whether the cause of suspension of the charging of the battery is a completion of the charging or an interruption of the charging by a user and as to be able to produce different outputs for the respective cases.
- In a fourth preferred embodiment, the controller performs control so that notification is made before the reproduction of the data is stopped when the charge detector detects the suspension of the charging of the battery.
- A second aspect of the invention provides a portable mobile unit comprising a memory for storing data; a controller for controlling reproduction of the stored data; and a remaining power detector for detecting remaining power of a battery, wherein the controller prohibits a start of reproduction of the data when the remaining power detector detects that the remaining power of the battery is smaller than a preset value.
- In a first preferred embodiment, the controller cancels the prohibition of reproduction of the data when a user makes a predetermined manipulation even if the remaining power of the battery is smaller than the preset value.
- In a second preferred embodiment, the controller performs control so that reproduction of the data is stopped after a lapse of an arbitrary preset time from a start of the reproduction of the data.
- In a third preferred embodiment, the controller performs control so that an alarm is generated before the reproduction of the data is stopped.
- The invention as described above can provide a portable mobile unit that is easy to use and can increase the speech time.

- Embodiments of the present invention will be hereinafter described in detail with reference to the accompanying drawings. Each embodiment will be directed to a cellular phone as a portable mobile unit. In FIGS.1-15, the same or equivalent components or steps are denoted by the same reference symbols. FIG. 1 is a front view showing the appearance of a portable mobile unit.
Reference numeral 101 denotes a transmission/reception antenna; 102, a receiver, and 103, a display for displaying various kinds of information; 104, shift/decision keys to be used in setting a function; 105, input keys (including numeral keys) to be used in specifying a telephone number or specifying a number during a function search; and 106, a microphone. The appearance and the components shown in FIG. 1 are common to the following embodiments. - A portable mobile unit according to a first embodiment of the invention will be described below with reference to FIGS.1-9. This portable mobile unit can reproduce a plurality of data (musical data etc.) stored therein. Further, provided with a charge condition detector (hereinafter referred to as “charge detector”) for detecting a condition of a battery being charged, the portable mobile unit can announce, by means of music selected by the user, that charging is being performed by starting reproduction of data when a start of the charging is detected by the charge detector. FIG. 2 is a block diagram showing the configuration of the portable mobile unit according to the first embodiment.
Reference numeral 201 denotes a radio frequency circuit (hereinafter referred to as “RF circuit”) having a transmission/reception function; 202, an audio circuit; 203, a controller for controlling the entire portable mobile unit; 204, an alarm device for alarming the user by sound or vibration; 205, a memory for storing programs necessary for operation of cellular phone functions, setting data, and data of musical information to be used for reproducing music; 208, a battery (rechargeable battery); 206, an external power input terminal to be used for charging thebattery 208; and 207, a charging circuit for charging thebattery 208.Reference numeral 209 denotes a charge detector for detecting a charging state of thebattery 208. - The operation of the portable mobile unit of FIG. 2 will be described below. During reception, an input signal received by the
antenna 101 is decoded by theRF circuit 201 and theaudio circuit 202 into voice, which is output to thereceiver 102. During transmission, voice that is input through themicrophone 106 is modulated by theaudio circuit 202 and theRF circuit 201 into a transmission signal, which is transmitted from theantenna 101. In the above operations, theRF circuit 201 and theaudio circuit 202 are controlled by thecontroller 203. - Next, a function of reproducing a plurality of stored data (musical data etc.) will be described. Examples of the data (musical data etc.) are sound data, text data, figure data, and video data. Examples of sound data are music, natural sound (e.g., sound of a water flow, a song of a bird, chirping of insects and a cry of an animal such as meow, bow-wow, moo, etc.), and artificial sound (e.g., a ring of a bell or a chime and a beep. The information of the plurality of data (musical data etc.) are stored in the
memory 205. When the function of reproducing the plurality of data (musical data etc.) is started by either predetermined manipulations of the user on theinput keys 105 and the shift/decision keys 104 or a transition of the portable mobile unit to a predetermined state, the plurality of data (musical data etc.) stored in thememory 205 are accessed sequentially by thecontroller 203 and reproduced as sound. As for the route of acquiring information of the above kind, data is prepared and stored in the portable mobile unit in advance, downloaded from an external system, or acquired in other ways. - When the portable mobile unit is set so as to start reproducing a plurality of data stored (such as musical data) at the time of starting battery charging, as a predetermined state, the
controller 203 inquires of thecharge detector 209 whether charging has been started and starts reproduction of the data (musical data etc.) by the above method upon detection of a start of charging. - FIG. 3 is a flowchart showing a process according to this embodiment. When a
battery 208 is mounted in the portable mobile unit capable of reproducing a plurality of data stored therein and an AC adapter is connected to it atstep 301 to charge thebattery 208, preliminary charging is performed atstep 302 and a red LED is turned on atstep 303. To confirm that charging has started, atstep 304 thecontroller 203 inquires of thecharge detector 209 whether charging has started. If charging is going on (yes), the process goes to step 305 (start of confirmation of an automatic reproduction mode) and main charging is started atstep 312. A method for setting the automatic reproduction mode will be described later. If charging has not started (no), the process goes to step 310, where occurrence of an error is announced. Atstep 311, the charging operation is stopped. - When the process goes to step305 (start of confirmation of an automatic reproduction mode), at
step 306 thecontroller 203 inquires of thememory 205 whether the automatic reproduction mode is set. If the automatic reproduction mode is set (yes), the automatic reproduction mode is started atstep 307, whereby step (A) is established in which musical information stored in thememory 205 is reproduced and output as sound from thereceiver 102 and/or the alarm means 204. If the automatic reproduction mode is not set (no), the start of the automatic reproduction mode is prohibited atstep 308. This is done by refraining from activating a program for the automatic reproduction function. - The portable mobile unit may be configured in such a manner that the reproduction time of data (musical data) is set at an arbitrary time. FIG. 4 is a flowchart showing a process corresponding to this case. FIG. 8A shows a display example of alarm notification corresponding to this case. When automatic reproduction is started at
step 307 in FIG. 3 and step (A) is established, the automatic reproduction is continued atstep 401. The process goes to step 402 (start of a check of a reproduction time), and atstep 403 thecontroller 203 judges whether the reproduction time has reached an arbitrary preset time (n minutes). Monitoring the reproduction time, thecontroller 203 compares the reproduction time with the arbitrary time (n minutes) that is preset in thememory 205. If the reproduction time has reached the arbitrary preset time (no), alarm notification is performed atstep 404 by displaying a picture as shown in FIG. 8A on thedisplay 103 and the automatic reproduction is stopped atstep 405. On the other hand, if the reproduction time has not reached the arbitrary preset time yet (yes), the process returns to step 401, where the automatic reproduction is continued. Since the user can set the reproduction time arbitrarily, selection can be made between an operation that data is reproduced for about one minute at the start of charging for only the notification purpose and an operation that data is reproduced for a desired time to allow the user to enjoy music. The device for performing the alarm notification is not limited to thedisplay 103 and may be performed by at least one of thedisplay 103, thereceiver 102, and thealarm device 204. In the above process, the alarm notification is performed after the execution ofstep 403 before the stop of the automatic reproduction. Alternatively, the automatic reproduction may be stopped without performing the alarm notification. - As a further alternative, reproduction of data (music) may be stopped when the
charge detector 209 detects that charging of the battery has been suspended after the data reproduction has started upon detection of a start of the charging by thecharge detector 209. FIG. 5 is a flowchart showing a process corresponding to this case. FIGS. 8B and 8C show display examples of alarm notification corresponding to this case. When automatic reproduction is started atstep 307 in FIG. 3 and step (A) is established, the automatic reproduction is continued atstep 501. Then, the process goes to step 502 (start of confirmation of charging). Atstep 503, to confirm that the charging is being continued, thecontroller 203 inquires of thecharge detector 209 whether the charging is being continued. If the charging is being continued (yes), the process goes to step 504 (start of a check as to whether the charging has completed). If it is judged atstep 503 that the charging is not being performed (no), alarm notification is performed at step 506 by displaying a picture as shown in FIG. 8B on thedisplay 103 and the automatic reproduction is stopped atstep 507. - After step504 (start of a check as to whether the charging has completed), at
step 505 thecontroller 503 inquires of thecharge detector 209 whether thebattery 208 has been charged up. If thebattery 208 has been charged up (yes), alarm notification is performed at step 506 by displaying a picture as shown in FIG. 8C on thedisplay 103 and the automatic reproduction is stopped atstep 507. At this time, an alarm sound may be generated before stopping the reproduction of data (music). For example, a peep as an alarm sound may be generated several seconds before stopping the reproduction of data (music). This allows the user to know in advance an approaching stop of reproduction of data (music) at the time of a completion or suspension of charging. If it is judged atstep 505 that thebattery 208 has not been charged up yet (no), the process returns to step 501, where the automatic reproduction is continued. - With the above process, data (music) can be stopped automatically when charging of the
battery 208 has been completed or suspended. The portable mobile unit may be configured in such a manner that when charging of thebattery 208 has been stopped, thecharge detector 209 recognizes whether the charging has been stopped due to charging-up of thebattery 208 or the user's interruptive manipulation and the notification method is changed depending on the cause. For example, after the judgment atstep 505, a second notification sound may be output from thealarm device 204 as the alarm notification at step 506. If charging is stopped though it is judged atstep 505 that thebattery 208 has not been charged up yet, a judgment can be made that the charging has been stopped due to the user's interruptive manipulation. Recognizing the reason of a stop of charging makes it possible to change the content of notification. For example, in the case of a stop of charging due to the user's interruptive manipulation, notification may be made by the second notification sound, that is, a notification sound that is different from an ordinary notification sound. This enables discrimination from a reproduction sound of data (music) that is generated at the time of completion of charging, that is, discrimination between completion and suspension of charging. - The device for performing the alarm notification is not limited to the
display 103 and may be performed by at least one of thedisplay 103, thereceiver 102, and thealarm device 204. In the above process, the alarm notification is performed after the judgment atstep - As shown in FIG. 6, the process that is executed after step (A) in FIG. 3 may be a combination of the processes of FIGS. 4 and 5. The process of FIG. 6 will be described below. Steps (A) to step505 (inquiry about whether the
battery 208 has been charged up) are the same as shown in FIG. 5,steps step 505 that thebattery 208 has not been charged up yet (no), the process goes to step 402 (start of a check of reproduction time). If thebattery 208 has been charged up (yes), alarm notification is performed atstep 601 and the automatic reproduction is stopped atstep 602. - The portable mobile unit may be configured in such a manner that the data reproduction start function can be set and cancelled selectively by the user so that the user cancel the data reproduction start function at the time of detection of a start of charging of the
battery 208 if the user does not want reproduction of data. Setting should be so made as to allow the user to set or cancel the data reproduction start function on a menu picture. FIG. 7 shows exemplary display pictures. A method for setting the automatic reproduction mode according to pictures displayed on thedisplay 103 will be described with reference to FIG. 7. In a reception standby state, the picture of part (a) of FIG. 7 is displayed. Automatic reproduction mode setting is included in the functions of the item “6: Display and function settings.” If the numeral key “6” of theinput keys 105 is depressed, the picture of part (b) of FIG. 7 appears. The automatic reproduction mode setting corresponds to the item “5: Automatic reproduction mode setting” in the picture of part (b) of FIG. 7. If the numeral key “5” of theinput keys 105 is depressed, the picture of part (c) of FIG. 7 appears. Setting corresponds to the item “1: Setting” in the picture of part (c) of FIG. 7. If the numeral key “1” of theinput keys 105 is depressed, the automatic reproduction setting is completed. The information of the automatic reproduction mode is stored in thememory 205. - A reproduction time is set according to display pictures shown in parts (b) and (c) of FIG. 9. To set a reproduction time, first the manipulations for the automatic reproduction mode setting that have been described above with reference to FIG. 7 are performed. Whereas the automatic reproduction mode setting is completed upon depressing the numeral key “1” of the
input keys 105 while the picture of part (c) of FIG. 7 is displayed, in the case where a reproduction time can be set the picture of part (b) of FIG. 9 appears upon depressing the numeral key “1” of theinput keys 105 while the picture of part (c) of FIG. 7 is displayed. If the user wants to set the reproduction time at 30 minutes, for example, heinputs 30 minutes by depressing the numeral keys “3” and “0” of theinput keys 105, whereupon the display picture of part (c) of FIG. 9 appears. The setting is completed when the user depresses the decision key of the shift/decision keys 104. This information is stored in thememory 205. - A portable mobile unit according to a second embodiment of the invention will be described below with reference to FIGS.10-14. This portable mobile unit can reproduce a plurality of data (musical data etc.) stored therein. Further, provided with a remaining power detector for detecting remaining power of a battery, the portable mobile unit refrains from starting to reproduce the data (musical data etc.) if the remaining power of the battery is smaller than a preset value even when the user has made a manipulation for starting reproduction of the data, and thereby prevents power consumption that would otherwise be caused by reproduction of the data (musical data etc.). FIG. 10 is a block diagram showing the configuration of the portable mobile unit according to the second embodiment.
Reference numeral 201 denotes an RF circuit having a transmission/reception function; 202, an audio circuit; 203, a controller for controlling the entire portable mobile unit; 204, an alarm device for alarming the user by sound or vibration; 205, a memory for storing programs necessary for operation of cellular phone functions, setting data, and musical information to be used for reproducing music; and 208, a battery (rechargeable battery).Reference numeral 1001 denotes a remaining power detector for detecting remaining power of thebattery 208. - The basic operation of the function of reproducing the plurality of stored data (musical data etc.) is the same as described above with reference to FIG. 2 and hence will not be described. When the user tries to activate the function of reproducing the plurality of stored data (musical data etc.) at the time of a start of charging by performing predetermined manipulations on the
input keys 105 and the shift/decision keys 104, thecontroller 203 inquires, of the remainingpower detector 1001, remaining power of thebattery 208 and judges whether the remaining power of thebattery 208 is greater than or equal to a threshold value that is large enough to secure a predetermined speech time. If the remaining power of thebattery 208 is greater than or equal to the threshold value, thecontroller 203 activates the function of reproducing the data (musical data etc.) If the remaining power of thebattery 208 is smaller than the threshold value, thecontroller 203 prohibits activation of this function. - FIG. 11 is a flowchart showing a process according to this embodiment. Part (d) of FIG. 14 shows a display example of alarm notification. These process and display example will be described below. When manipulations for starting automatic reproduction are performed at
step 1101 in the portable mobile unit capable of reproducing a plurality of data (musical data etc.) stored therein, the process goes to step 1102 (start of a check of remaining battery energy). To check remaining power of thebattery 208, atstep 1103 thecontroller 203 inquires, of the remainingpower detector 1001, remaining power of thebattery 208 and judges whether the remaining power of thebattery 208 is greater than or equal to a threshold value that is large enough to secure a predetermined speech time. If the remaining power of thebattery 208 is greater than or equal to the threshold value (yes), the process goes to step 1104, where automatic reproduction is started. As a result, step (B) is established in which musical information stored in thememory 205 is reproduced and output as sound from thereceiver 102 and/or the alarm means 204. If the remaining power of thebattery 208 is smaller than the threshold value (no), alarm notification is performed atstep 1105 by displaying a display picture as shown in part (d) of FIG. 14 on thedisplay 103 and the start of the automatic reproduction function is prohibited atstep 1106. The by start of the automatic reproduction function is prohibited by refraining from activating a program for the automatic reproduction function. The device for performing the alarm notification is not limited to thedisplay 103 and may be performed by at least one of thedisplay 103, thereceiver 102, and thealarm device 204. In the above process, the alarm notification is performed after the judgment atstep 1103 before the prohibition of the start of the automatic reproduction function. Alternatively, the start of the automatic reproduction function may be prohibited without performing the alarm notification. - The portable mobile unit may be configured in such a manner that the start of reproduction of data (musical data) is permitted by a predetermined manipulation even if remaining power of the
battery 208 is smaller than the threshold value when the user has made a manipulation for starting reproduction of the data. A process corresponding to this case will be described below with reference to FIGS. 12 and 14. This process makes it possible to start reproduction of data (musical data) upon a manipulation by the user in a case where the user allows the communication function to be disabled. FIG. 12 is a flowchart of this process and (a), (b), and (d) of FIG. 14 show display examples of alarm notification. Step 1101 (manipulations for starting automatic reproduction) to step 1103 (inquiry about remaining battery energy) are the same as the corresponding steps in FIG. 11 and hence will not be described. If it is judged atstep 1103 that remaining power of thebattery 208 is smaller than the threshold value (no), the process goes to step 1201 (start of confirmation of automatic reproduction). Atstep 1202, a picture for confirmation as shown in part (a) of FIG. 14 is displayed on thedisplay 103. If the user depresses the numeral key “1” (yes) of theinput keys 105 atstep 1203, the process goes to step 1204, where a picture as shown in part (b) of FIG. 14 is displayed. Automatic reproduction is started atstep 1205. On the other hand, the user depresses the numeral key “2” (no) of theinput keys 105 atstep 1206, the process goes to step 1207, where a picture as shown in part (d) of FIG. 14 is displayed. The start of the automatic reproduction function is prohibited atstep 1208. If it is judged atstep 1103 that the remaining power of thebattery 208 is greater than or equal to the threshold value (yes), alarm notification is performed atstep 1204 and automatic reproduction is started atstep 1205. The device for performing the alarm notification is not limited to thedisplay 103 and may be performed by at least one of thedisplay 103, thereceiver 102, and thealarm device 204. - In the above process, the alarm notification is performed at
step 1207 that followsstep 1206 and atstep 1207 that followsstep - The above process enables the user to start reproduction of data (musical data) by performing a manipulation while a menu picture is displayed in a case where he allows the communication function to be disabled.
- The portable mobile unit may be configured in such a manner that automatic reproduction is stopped after a lapse of an arbitrary preset time from its start. This makes it possible to prevent power consumption due to a failure of stopping automatic reproduction.
- The portable mobile unit may be configured in such a manner that the reproduction time of data (musical data) is set at an arbitrary time. Automatic reproduction of data (musical data) is stopped after a lapse of a preset time from its start. FIG. 13 is a flowchart showing a process corresponding to this case. Part (c) of FIG. 14 shows a display example of alarm notification corresponding to this case. When automatic reproduction is started at
step 1104 in FIG. 11 and step (B) is established, the automatic reproduction is continued atstep 1301. The process goes to step 1302 (start of a check of remaining battery energy). Then, to check remaining power of thebattery 208, atstep 1303 thecontroller 203 inquires, of the remainingpower detector 1001, remaining power of thebattery 208 and judges whether the remaining power of thebattery 208 is greater than or equal to a threshold value that is large enough to secure a predetermined speech time. If the remaining power of thebattery 208 is greater than or equal to the threshold value (yes), the process goes to step 1304 (start of a check of a reproduction time). If it is judged atstep 1303 that the remaining power of thebattery 208 is smaller than the threshold value (no), alarm notification is performed atstep 1306 by displaying a picture as shown in part (c) of FIG. 14 on thedisplay 103 and the automatic reproduction is stopped atstep 1307. - After step1304 (start of a check of a reproduction time), at
step 1305 thecontroller 203 judges whether the reproduction time has reached an arbitrary preset time (n minutes). Monitoring the reproduction time, thecontroller 203 compares the reproduction time with the arbitrary time (n minutes) that is preset in thememory 205. If the reproduction time has reached the arbitrary preset time (no), alarm notification is performed atstep 1306 by displaying a picture as shown in FIG. 8A on thedisplay 103 and the automatic reproduction is stopped atstep 1307. On the other hand, if the reproduction time has not reached the arbitrary preset time yet (yes), the process returns to step 1301, where the automatic reproduction is continued. The device for performing the alarm notification is not limited to thedisplay 103 and may be performed by at least one of thedisplay 103, thereceiver 102, and thealarm device 204. - With the above process, not only is the user allowed to enjoy music for a desired time but also useless power consumption due to a failure of stopping reproduction can be prevented because the reproduction is stopped after a lapse of the preset time.
- In the above process, the alarm notification is performed after the judgment at
